Conclusions:
The particle size distribution of the test item was found to be [125 μm; 1000 μm]. Less than 10% of the test item is larger than 1 mm and more than 90% is larger than 125 μm.
Executive summary:

The study was performed according to CIPAC methods MT 169 & 170, using the sieving method.

The particle size distribution of the test item was found to be [125 μm; 1000 μm]. Less than 10% of the test item is larger than 1 mm and more than 90% is larger than 125 μm.
